TIRE questions

I currently have 235/75/15 michelin tires on my 96 blazer. These are what came with it. I am wondering what people would recommend putting on my truck, should i stay with the same size, same brand, and so on. I need to get new tires before deer hunting! I am also looking for some tires that are affordable (i am a college student) thanks.

Most people seem to run 235/75/15's if the truck is a 4wd. Most all terrain tires in that size are around $100 a piece so shop around.
